Here is a piece of my personal review:
AngularJS 官网提到了其适合的项目任务属性：面对需要高性能的 dom 操作，比如拖拽，使用 watch 是不合适的，所以 angularjs 也让咱们可以直接使用 jQuery 操作dom，而不做任务的 digest.
In the tutorials of AngularJS, we found Google says that AngularJS watch/digest is not fit for busy DOM operation, like DragNDrop. So they suggest us not use scope digest in these scenarios, instead, use jQuery directly. (And they enable us to do so within AngularJS framework)
One more thing, the new JS API object.observe is on the way for many browsers (Already shipped with Chrome: http://caniuse.com/#feat=object-observe since V35). The current AngularJS dirty check is going to be replaced by the new JS API. By the time, it’s not doubt that AngularJS is not more THAT power consuming in many cell phones.
再者，我们选择 AngularJS 的原因，就是因为相信 Google 的开发团队的责任心与能力。 我们不想选择一个5年后可能会不再有人维护更新的框架，而 Google 应该不会轻易放弃 AngularJS。
Besides, one of the reasons we picked AngularJS as our framework is that we trust the sustained power and responsibilities of Google, the Internet Giant. We wouldn’t like to build our apps on a framework that is going to be abandoned in 5 years. We believe that the current activities of development of AngularJS from Google guys and its community are going to be being burnt on. That’s Google, you know.
And, we bet Chrome ecosystem would be a great supporter of AngularJS. You know why.
最后， AngularJS 拥有完整财力后盾支持 ，使他们的各种社区与教程，会是越来越多人选择学习的不二之选——前提是可以翻墙——所以，咱们招人会越来越容易——其实我们团队这么多人，也都是在短时间之内学会 AngularJS 的，这足以说明AngularJS 并不是企业人力资源的 bombshell 。
Finally, AngularJS has a great financial support, which is diverting a lot of attentions of many front-end engineers to it through their excellent tutorials and communities. So it would be much easier for enterprise projects to recruit talents in the future. Think about our team — many of us are not competent while we joined the team. But all of us got started and sophisticated very fast, aren’t we?
To be continued.
